Fast Huygens’ sweeping methods for multiarrival Green’s functions of Helmholtz equations in the high-frequency regime

Abstract

Multi-arrival Green’s functions are essential in seismic modeling, migration and inversion. HuygensKirchhoff integrals provide a bridge to integrate locally valid first-arrival Green’s functions into a globally valid multi-arrival Green’s function. We design robust and accurate finite-difference methods to compute first-arrival traveltimes and amplitudes so… (More)
